To find the length of the shortened ribbon, we need to subtract the length cut off from the original length of the ribbon.
The original length of the ribbon is 618 feet, and the amount cut off is 2112 feet.
Since 2112 feet is greater than 618 feet, it indicates a misunderstanding, as you cannot cut off more material than you have.
However, if we proceed with the assumption that you meant to say the ribbon had a modified length after being cut or if there was a typographical error, we reinterpret the question based on its structure.
Let's calculate:
Length of ribbon after cutting: \[ \text{New Length} = \text{Original Length} - \text{Cut Off} = 618 - 2112 \]
This results in: \[ 618 - 2112 = -1494 \]
The calculation shows a negative length which is not possible.
If none of the responses provided fit a plausible real-world answer, please verify the initial parameters (original length or inches cut off), or clarify any specifics needed to resolve this riddle.
